Membrane Separations in Biorefineries by Frank Lipnizki, Alfa Laval
Abstract: Membrane processes have the potential to become a key separation unit in the concept of biorefineries considering their high selectivity and low energy consumption. Potential key applications can be found in both the production and water loop of biorefineries. The presentation will cover membrane and membrane hybrid processes in the production and water loop of biorefineries.

Abstract: The bioased industry is putting significant effort into research and development to replace refined sugars by much cheaper non-food renewable feedstocks for the production of bio-fuels and chemicals. Although this obviously increases sustainability, it also brings about a number of technological challenges due to the higher complexity of these secondary substrates. Biomass hydrolysates, for example, can contain high concentrations of sodium and potassium that inhibit fermentation and hence need to be reduced. The commonly used ion-exchange processes carry high operational costs and generate a waste stream through the use of chemicals for regeneration. Electrochemical pre-treatment of biomass hydrolysates with membrane capacitive deionisation or MCDI could provide a lower cost alternative with minimal waste generation.

Abstract: Despite the recent progress in biotechnology, several biobased processes are still plagued by limited product titers and low volumetric productivities due to product inhibition. Other processes suffer from side reactions decreasing the yield. Integrating the bioprocess with a suitable in-situ product recovery (ISPR) technique is an interesting strategy to overcome these problems. The presentation will show that pervaporation can be successfully implemented for in-situ water removal from condensation reactions, product purification and dehydration or concentration of solvent solutions from organophilic pervaporation.
